Definitions

  • the present invention relates to sliding bearings having a sintered metallic sliding layer and a metal backing layer, and more particularly, but not exclusively, to sliding bearings for connecting rod small end bearings, and thrust washers for bearing shells in crankshaft main bearings.

  • Bearing bushes are hollow cylindrical bearing liners, that may be solid sleeve bushes, split bushes (in which a strip is formed into a cylinder with butt-jointed ends) or clinch bushes (like split bushes, additionally provided with mutual engagement features on the ends of the strip).
  • journal e.g. gudgeon pin/wrist pin

  • the carbon nanostructures may provide self-lubrication properties, which reduce the friction coefficient and wear rate of the bearing, and may reduce the operating temperature of the bearing. Further, the carbon nanostructures may reduce the propagation of cracks in the lining layer. Yet further, the carbon nanostructures may stabilise grains in the granular structure of the lining layer when the grain boundaries become weakened at high operating temperatures, reducing their relative movement and reducing material wear of the lining layer.
  • copper-based matrix is meant pure copper (apart from incidental impurities) or a copper- based alloy comprising at least ⁇ 50%wt of copper.
  • the backing layer may be a steel backing layer.
  • the lining layer may comprise 0.5 - 4.0%wt carbon nanostructures.

  • the lining layer may comprise nickel in a proportion of up to 1.5%wt.
  • the nickel may provide increased corrosion resistance.
  • the carbon nanostructures may be at least partially metal-coated carbon nanostructures.

  • the backing layer 2 is steel
  • the lining layer 3 is a copper-based composite lining layer 3, comprising carbon nanotubes 5 in a copper- based alloy matrix 6.
  • composition of the lining layer 3 is:
  • carbon nanostructures e.g. carbon nanotubes
  • the blank is cut from a sheet of backing material having a sintered lining layer, and formed by a sintering process, as follows: the carbon nanostructures are blended together with the other ingredients in powdered form; the composite powder is distributed onto a sheet of backing layer material; the structure is sintered at high temperature in an inert or other non- oxidising environment; the structure is rolled before being sintered a second time; and the blanks are stamped out from the sintered structure.
  • the present invention is also applicable to sintered lining layers on other sliding bearings, including thrust washers (in which the lining layer is provided on an axial face of a generally semi-annular backing layer, facing the counterface of a crankshaft web).
  • a carbon nanostructure is any carbon allotrope composed entirely of carbon, in the form of a hollow sphere, ellipsoid, or tube having a sub-micron diameter.
  • the incorporation of carbon nanostructures into the metallic matrix increases the strength, hardness and wear resistance of the composite lining layer, whilst still permitting good conformability of the bearing.
  • the exposed carbon nanostructures also increase the lubricious properties of the free surface, reducing friction of the metallic matrix when the shaft contacts the bearing lining layer, for example when the engine starts and before adequate lubrication oil has been provided to the bearing (e.g. by splash lubrication).
  • carbon nanostructures may be more flexible and have higher tensile strength than the micro-particulates that it is currently known to incorporate into a metal matrix to form a composite layer.
  • the carbon nanostructures also reinforce the metallic matrix. Additionally, in the case of carbon nanotubes, they may enhance thermal dissipation through the layer, e.g. away from the free surface of the lining layer.
  • the carbon nanostructures may be at least partially metal-coated, to enhance their bonding with the copper-based matrix and may enhance their blending with the other powdered ingredients to form the mixture for sintering.
  • coating with a material present in the matrix reduces the risk of formation of undesirable intermetallics that comprise other materials.
  • the metallic coating is applied to the carbon nanostructures by a process that may be an electroless chemical treatment, physical vapour deposition or thermal decomposition methods.
  • the carbon nanostructure may be a functionalised carbon nanostructure, such as a functionalised single wall nanotube (SWNT) or multi-wall nanotube (MWNT).
  • SWNT functionalised single wall nanotube
  • MWNT multi-wall nanotube
  • an aggressive mechanical milling process may be used, in which the carbon nanostructures and the metal powder are milled together with a media that results in the metal powders being broken apart and the carbon nanostructures becoming incorporated into the metal particles. These metal-carbon nanostructure granules are then blended with the rest of the powder matrix material and disperse much more easily than the carbon nanostructures alone.
  • the illustrated embodiment concerns a composite layer in which carbon nanotubes are incorporated into a metallic matrix
  • other types of carbon nanostructures may alternatively or additionally be incorporated, such as hollow spheres (e.g. C 52 , C 6 o, C 70 , C 76 , C 8 4, etc.) or ellipsoids.
  • the sliding bearing may be a bearing shell or a thrust washer, which is inserted into the bearing assembly of an engine, such as an automotive engine.
